A lug 62 extending upward from latch 47 is provided with a set screw 63 adapted to engage member 36 and limit the movement of clamp 47 to the right, as shown in the drawings.

A bottom support 64 is provided with pivots 65 adapted to engage notches 66 in downward extensions of frame 37. Bottom 64 is also provided with pins 67 which may be placed in any of a series of holes 68 in links 69 pivoted at 7 O to the outer ends of arms 45. I

Above the hopper of the discharge device there is mounted a shaft 71. This may be connected to an agitating device for assisting in feeding material to the hopper, as is well known in the art. Shaft 71 is provided with an eccentric 72 connected by a link 73 to a pivot 74 on an arm 75 of a rock shaft 76. Another arm 77 on rock shaft 76 is pivoted to a lifting member 78. A lifting hook 79 is pivoted at 80 to member 78, and is provided with a notch 81 adapted to engage a pin 8201i lever 18. A spring 83 normally presses lifting hook '79 to the position in which it is shown in Figs. 1, 2 and 4. A link 84 pivoted at 85 to a fixed bracket carries a roller 86 adapted to engage hook member 79 and press it into operative position. A spring 87 connects link 84 with a pin 88 directly above pivot 85 and tends to hold link 84 in a sliding position on either side of the vertical to which it is moved. Link '84 is provided with a pin 89 working in a ing spout so as to receive material discharged through the filling opening and through spout 44 into the bag. hen suflicient material has been fed into the bag to overbalance the scale beam so as to result in a downward movement of frame 37, set screw 35 engages the end of trigger 29 and releases latch 24. Thereupon, spring 16 pulls the gate downward to its closed position, as shown in F ig. 3, swinging the upper end of lever 18 to the right and forcing latch 24 outward to the position in which it is shown in Fig. 3.

hen member 60 is moved downward to the position in which it is shown in Fig. 3, it engages roller 59 and oscillates clamp 47 to release it from the bag and also through pin and slot connection, 52, 53, raises catch 54 to release carrier 42. Thereupon, the weight of the bag upon spout 44 and bottom 64 overcomes spring 46 and moves the bottom downward to slanting position, and also the filling spout 44 to the position in which it is shown in Fig. 4. Thereupon, the bag slides off of the bottom and spout. Thereafter, spring 46 immediately raises carrier 42, spout 44 and bottom 64 to the position in which they are shown in Figs. 1 to 3. With the parts in this position, an empty bag may be placed upon the spout. Thereafter, the operator depresses handle 92 thus swinging link 84 to the right until roller 86 contacts the lower end of member 79. Thereupon, spring 87 tends to continue the movement of the link until spring 83 is overcome and the hook is positioned beneath pin 82. It will be readily understood that as shaft 71 is rot-ating constantly member 78 continues to be reciprocated vertically. Upon the next upward movement of members 78 and 79 after the shifting of handle 92, the engagement of hook S1 with pin 82 raises lever 18 and opens the gate. If desired, when the bag is placed upon the spout, the outer end of member 60 may be depressed and the clamp tightened to place catch 54 in holding position. \Vhen lever 18 moves upward, member 60 will oscillate on its pivot and not interfere with the holding of the clamp and catch. It will be understoodthat frame 37 along with clamp 47, arm 58 and roller 59 are in slightly lowered position when the trip is actuated to close the gate and immediately after the bag slips off of the spout and bottom frame 37 returns upward to its normal position which is normally suficient to raise it above member 60. Thereupon, spring 50 swings the clamp towards clamping position until stopped by set screw 63. This prevents the catch from moving so far as to interfere with the proper return of carrier 42 to its filling position. The upward movement of lever 18 engages handle 92 and thereby swings links 84 to the position in which it is shown in Figs. 1 and 2. The parts are thereby returnedto the origi nal position in which they are shown in Fig. 1 and the operation is repeated.
